So, I have installed FusionPBX on several Debian 13 bases. No audio when calling into a conference bridge. Normally that is my first litmus test of system functionality. Set up an extension, set up a conference bridge, call into bridge. No audio, but the call connects into the bridge and stays up.. Used the install script on the fusionpbx website. I have tried the cd* and ultra* music-on-hold profiles, to no avail.

Is there anything at fs_cli I should be looking for?

Outbound calls 2 way audio works great otherwise.

Is this 5.5.7?
 
Also. While testing this, 5.5.6 On Debian 13, I thought maybe DTMF wasn't working right. I called a toll free number and my DTMF wasn't breaking the IVR.

Luckily I retested on 8042221111 and it echoed back good DTMF testing.

Thank You testcall.com
 
New Issue, for conversation purposes.

I have several Yealink Phones. T46Us and T48G. They are registered to FusionPBX. When I do Status::Registrations::Checkbox a registered line::Select UNREGISTER. The extension should simply unregister on the phone, I'd expect. Instead, the phone reboots 100%.

That is not the expected behaviour. Is it? No output on fs_cli. So I think there is supposed to be a phone unregister command instead of a phone reboot command.

There is also a REBOOT command on this page as well... When I click it, while a phone is checked, the phone reboots, as expected.

fs_cli output:
2026-02-12 11:14:43.785662 98.80% [NOTICE] switch_cpp.cpp:1466 [event_notify] command reboot [email protected] vendor yealink

@herbertshades Wish granted. I'm not opinionated on this one. If you upgrade to latest 5.5 code or master branch UNREGISTER will only unregister, and it will not reboot the endpoint. The REBOOT button will continue to reboot the phone.
 
@herbertshades For no audio in a conference... I would ask if your PBX is behind NAT? Hosting services like Amazon or Google hosting? Or is your server on a public IP address? The more NAT is involved, the more it has a chance to interfere with audio.

Are the Yealink phones provisioned with FusionPBX or manually set up? If manually, then you may not have rport set to true or enabled.
 
@herbertshades here is a handy upgrade script to get you up to FusionPBX 5.5.7

Code: 
#!/bin/bash
cd /var/www/fusionpbx
git stash
git pull
git checkout 5.5
git branch
git pull
mkdir /var/run/fusionpbx
chown -R www-data:www-data /var/run/fusionpbx
php /var/www/fusionpbx/core/upgrade/upgrade.php --schema

Dang it @kenn10 - Thank You!

As I ran these commands, a few threw up errors. Here is what was the absolute clean run.
Code: 
#!/bin/bash
cd /var/www/fusionpbx
git config --global --add safe.directory /var/www/fusionpbx
git stash
git pull
git checkout 5.5
git branch
git pull
mkdir /var/run/fusionpbx

I will report on the results shortly. Oh, and I haven't forgotten my commit to document the IMT setup.

I probably created the safe.directory previously because I haven't run into that error on current upgrades. Good catch for the script.

Obviously, on the checkout command, you will change 5.5 to 5.6 when released and so forth.

No NAT. In one setup, I have the PBX on VLAN X and the phones in VLAN Y. This is typical setup for our environment. The PBX set up on Debian 12, with the Yealink phones, conference works, PSTN works. Debian 13 is where the conference doesn't work, although calls to the PSTN work fine. In a different setup all both the servers on Debian 12 and 13 are on the same LAN segment as the phones. Conference and PSTN work on Debian 12. On Debian 13, pstn works, conference no.

I will re-run setup on Debian 13 and ensure I am on 5.5.7; and report.

Upgrade worked great for me on our 3 servers. On our primary server with HostMedia U.K. in London that includes free weekly backups, we're up to 17 extensions in 3 states including 4 cellphones (2 iPhones and 2 Android phones), 4 tablets, and 3 iMacs plus some DAP devices as well as Yealink and Polycom/OBi phones. Audio is flawless using desktop phones and both Groundwire and Zoiper 5.

Update ... Reinstalled Debian 13, installed FusionPBX anew, good to version 5.5.7.
Set up extension, setup conference. Called into conference. On audio from Conference, but audio is good going into FusionPBX according to trusty tcpdump, which isn't installed by default :(.

Anywho, looking at fs_cli, I see this ....

Is something breaking when installing on Debian 13, but not on Debian 12?

Doing a simple find / -name conf-alone.wav gives no results.
 
Are you creating a conference (Applications > Conferences) or are you creating a conference room (Applications > Conference Center) ?? A conference works fine and everyone can talk to each other but if you create a conference room, the moderator must press the * key to unmute participants. At least that is how it works for me on Debian-12.

I see the sound file on my system so if you don't have it in the directory I show below, post over on the FusionPBX site. Keep in mind there are 4 subdirectories under /usr/share/freeswitch/sounds/en/us/callie/conference/ , i.e., 8000,16000,32000,48000 which are used according to the CODEC you are using. I use g,722 internally. If you have your default CODECs set to something unusual like OPUS and don't have other things set in Default Settings for FusionPBX, you might run into issues.

The fact that there is not one of the 4 subdirectories in front of conf-alone.wav makes me suspect something is awry with your install on Debian-13 and need to post on their forum for @markjcrane to examine. He does not monitor this forum as frequently as his own.

I finally got posting permissions on pbxforums! I will post there.

I am doing Application::: Conference.

This only happens (the malfunction) on Debian 13. I can install umpteen times on Debian 12 and it works great.

Thank You @kenn10
